Design sequence for a LC-tank voltage controlled oscillator in CMOS for RF

Published: 04 September 2004 Publication History

Abstract

A design sequence for a LC-tank Voltage Controlled Oscillator - VCO - in CMOS for Radio Frequency is presented this paper. Details about the design of the components are shown. Among these details, it is a method to reach the active components (transistors) based on simulations using models given by the foundry. A VCO with a frequency range from 2.4 GHz to 2.5 GHz has been designed to validate the method. Due to access facilities it had been chosen the AMS 0.35 μm CMOS as fabrication technology. The VCO had been fabricated and the measurements done are compatible with the simulations. The good agreement between the measurements and the simulations shows that the design sequence is correct.
